Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a hidden handle mold for vehicles with a mold closing and error prevention device. Background Technology

[0002] Currently, in the production and design of injection molds, two or more sliders are usually used to close in the mold closing direction to form the product's molding cavity. Ejector pins are set at the bottom of the molding cavity to eject the product from the molding cavity. Especially for the hidden door handles used in car doors, they usually include two opposing housings. An electronic control element is set between the two housings to control the opening action of the handle. Therefore, the housings usually have an arc curve adapted to the car door and are relatively thin. Thus, the reliability of the ejection mechanism of the hidden door handle for car doors is particularly important.

[0003] However, both the molding slider and the ejector pin rely on the mold opening action of the press. Furthermore, during the mold closing process, the ejector pin and its ejector plate need to return to their original position under the action of the spring. At this time, the slider also gradually moves towards the molding cavity under the action of mold closing. In some cases, in order to improve production efficiency, the mold closes too quickly. If the slider has reached the predetermined mold closing position before the ejector pin has fully returned to its original position, interference will occur between the two, resulting in mold damage. Therefore, it is necessary to provide a mold that can ensure working efficiency and stable and reliable mold closing action. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hidden handle mold for vehicles with a mold closing and error prevention device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A concealed handle mold for vehicles with a mold-closing error prevention device includes:

[0007] The upper module includes an upper template, an upper forming block and a diagonal tie rod set on the upper template;

[0008] The lower module includes a lower template, and a lower molding block and a side slider assembly that close together with the upper molding block during the mold closing action. The side slider assembly includes a drive slider and a molding slider that are fixedly connected. The diagonal tie rod passes through the drive slider. The molding slider, the lower molding block, and the upper molding block constitute the molding cavity of the automotive hidden door handle.

[0009] The demolding assembly includes an ejector plate disposed below the lower mold plate, and a plurality of ejector units and anti-misalignment posts disposed on the ejector plate. The ejector units are inserted into the lower molding block along the length of the automotive hidden door handle and are spaced apart on both sides of the end of the automotive hidden door handle. The anti-misalignment posts are disposed at both ends of the drive slider and are located outside the molding cavity. The drive slider is provided with a positioning area that matches the anti-misalignment posts. In the mold-closed state, the anti-misalignment posts are spaced apart from the positioning areas by an anti-misalignment gap. The anti-misalignment gap matches the mold opening stroke of the side slider assembly. Under the action of mold opening, the anti-misalignment posts move upward with the ejector plate and enter the positioning area.

[0010] Furthermore, the positioning area is arranged between the driving slider and the forming slider, and the positioning area is set to open toward the side away from the forming cavity.

[0011] Furthermore, the lower module is also provided with a guide block, and guide edges are extended on both sides of the drive slider. The guide block is pressed on the guide edges, and the anti-misalignment post is located at the bottom of the drive slider in the mold closing state and is close to the guide edges.

[0012] Furthermore, the lower molding block is provided with a plurality of first cooling structures spaced apart along the length of the vehicle hidden door handle, and a second cooling structure is provided corresponding to both ends of the vehicle hidden door handle, and the ejector pin is arranged between the first cooling structure and the second cooling structure;

[0013] The molding slider has multiple first cooling structures along the length of the vehicle's hidden door handle.

[0014] Furthermore, the first cooling structure refers to a first channel disposed within the lower molding block and the molding slider, and a partition placed within the first channel. The partition has a notch corresponding to the end of the first channel, and the partition divides the first channel into a first part and a second part. The notch connects the first part and the second part.

[0015] Furthermore, the second cooling structure includes a second channel extending vertically and close to both sides of the vehicle's hidden door handle, a third channel communicating with the periphery of the lower molded block, and a spiral blade placed in the second channel, the second channel communicating with the third channel, the spiral blade defining a spiral path within the second channel.

[0016] Furthermore, the lower template is provided with a first rotating shaft, the first rotating shaft is fitted with a damping sleeve and a rotating block, and the ejector plate is provided with a first abutting block corresponding to the lower end of the rotating block;

[0017] The upper template is provided with a limiting rod that fits on the outer edge of the ejector plate, and the lower template is also provided with a second abutting block. The first abutting block and the second abutting block are arranged on both sides of the limiting rod. The rotating block abuts against one side of the limiting rod in the mold closing state, and the trajectory of the limiting rod and the rotating block are not tangent.

[0018] Furthermore, the outer boundary of the upper template is provided with a T-shaped block, and the outer boundary of the lower template is provided with two clamping blocks that cooperate with the T-shaped block. A spring is provided between the two clamping blocks, and a mounting base is provided on the outer cover of the two clamping blocks.

[0019] Furthermore, a strong tie rod is detachably provided between the outer boundaries of the upper module and the lower template.

[0020] Furthermore, the ejector plate is provided with a contact block, and the lower module includes a base plate, on which a positioning sensor is provided opposite to the contact block.

[0021] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0022] This invention features ejector pins and anti-misalignment posts on the ejector plate. The ejector pins are positioned inside the molding cavity, while the anti-misalignment posts are positioned outside the molding cavity and correspond to the drive slider. In the mold-closed state, the anti-misalignment posts return to their original position with the ejector plate and are stored in the lower mold plate. In the mold-open state, the side slider assembly slides under the action of the inclined tie rod, and then the press actuates the ejector plate to push it upward. At this time, the ejector pins push out the hidden door handle of the car door, while the anti-misalignment posts extend into the positioning area between the drive slider and the molding slider. When the mold is closed again, the ejector plate first returns to its original position via the spring on it and disengages from the positioning area. This ensures that the side slider assembly can only close the molding cavity under the action of mold closing when the ejector plate returns to its original position, preventing interference between the side slider assembly and the ejector pins and ensuring the reliability of the injection molding production of the hidden door handle for automobiles.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0048] like Figure 1-10 As shown, a vehicle concealed handle mold with a mold-closing error-proofing device includes:

[0049] The upper module 1 includes an upper template 1.1, an upper forming block 1.2 and a diagonal tie rod 1.3 disposed on the upper template 1.1;

[0050] The lower module 2 includes a lower template 2.1, a lower molding block 2.2 that closes with the upper molding block 1.2 during the mold closing action, and a side slider assembly. The side slider assembly includes a drive slider 2.3 and a molding slider 2.4 that are fixedly connected. A diagonal tie rod 1.3 passes through the drive slider 2.3. The molding slider 2.4, the lower molding block 2.2, and the upper molding block 1.2 constitute the molding cavity 3 of the automotive hidden door handle 19.

[0051] The demolding assembly includes an ejector plate 4 disposed below the lower mold plate 2.1, and several ejector pins 4.1 and anti-misalignment posts 4.2 disposed on the ejector plate 4. The ejector pins 4.1 are inserted into the lower molding block 2.2 along the length of the vehicle hidden door handle 19 and are spaced apart on both sides of the end of the vehicle hidden door handle 19. The anti-misalignment posts 4.2 are disposed at both ends of the drive slider 2.3 and are located outside the molding cavity 3. The drive slider 2.3 is provided with a positioning area 5 that matches the anti-misalignment posts 4.2. In the mold-closed state, the anti-misalignment posts 4.2 are spaced apart from the positioning area 5 by an anti-misalignment gap, which matches the mold opening stroke of the side slider assembly. Under the action of mold opening, the anti-misalignment posts 4.2 move upward with the ejector plate 4 and enter the positioning area 5.

[0052] In the mold-closed state, the anti-misalignment post 4.2 returns to its original position with the ejector plate 4 and is stored in the lower mold plate 2.1, thus avoiding interference with the drive slider 2.3. In the mold-open state, the side slider assembly slides under the action of the tie rod 1.3, and then the press actuates the ejector plate 4 to push it upward. At this time, the ejector pin 4.1 pushes out the hidden door handle, while the anti-misalignment post 4.2 extends into the positioning area 5 between the drive slider 2.3 and the molding slider 2.4. When the mold closes again, the ejector plate 4 returns to its original position first, causing the anti-misalignment post 4.2 to disengage from the positioning area 5. This ensures that the side slider assembly can close the molding cavity 3 under the action of mold closing only when the ejector plate 4 returns to its original position, preventing interference between the side slider assembly and the ejector pin 4.1, and ensuring the reliability of the injection molding production of the hidden door handle 19. This method also helps to control the production rhythm of the hidden door handle 19.

[0053] The ejector plate 4 is preferably returned to its original position by a spring 14. The return method of the ejector plate 4 is a conventional setting in this field and will not be described in detail here.

[0054] like Figure 2 As shown, specifically, the drive slider 2.3 and the forming slider 2.4 are fixed together by bolts and are both located in the sliding direction of the side slider assembly. The positioning area 5 is arranged between the drive slider 2.3 and the forming slider 2.4 to ensure that the anti-misalignment post 4.2 can block the drive slider 2.3 in an abnormal state to prevent the forming slider 2.4 from damaging the ejector pin 4.1. The positioning area 5 is set to open towards the side away from the forming cavity 3. This arrangement is beneficial for the anti-misalignment post 4.2 to enter the positioning area 5 in the mold opening state.

[0055] from Figure 4 As can be seen, specifically, the lower module 2 is also provided with a guide block 2.5, and the two sides of the drive slider 2.3 are provided with guide edges 2.41. The guide block 2.5 is fixedly set on the lower template 2.1, and the guide block 2.5 is pressed on the guide edge 2.41, thereby limiting the vertical movement of the side slider assembly. The anti-misalignment post 4.2 corresponds to the bottom of the drive slider 2.3 in the mold closing state and is set close to the guide edge 2.41. In this way, by limiting the sliding action of the side slider assembly, the accurate matching of the anti-misalignment post 4.2 and the positioning area 5 is ensured.

[0056] In other embodiments, in order to improve the production efficiency of the automotive hidden door handle 19, it is necessary to cool the molded component sufficiently to ensure product demolding efficiency and molding quality, and to quickly enter the injection molding cycle of the next product. For this purpose, the lower molding block is provided with a plurality of first cooling structures 6 spaced apart along the length direction of the automotive hidden door handle 19, and a second cooling structure 7 is provided corresponding to both ends of the automotive hidden door handle 19. The ejector pin 4.1 is arranged at intervals between the first cooling structure 6 and the second cooling structure 7.

[0057] from Figure 10 As can be seen, the molding slider 2.4 is provided with multiple first cooling structures 6 along the length of the vehicle hidden door handle 19. Through the above improvements, the periphery of the molding cavity 3 is fully cooled, and the ejector pins 4.1 are arranged between the cooling positions, which is conducive to the rapid demolding of the product.

[0058] like Figures 5 to 7 As shown, specifically, the first cooling structure refers to the first channel 6.1 disposed within the lower molding block and the molding slider 2.4, and the partition 6.2 placed within the first channel 6.1. The partition 6.2 has a notch 6.3 corresponding to the end of the first channel 6.1. The partition 6.2 divides the first channel 6.1 into a first part and a second part. The notch 6.3 connects the first part and the second part, so that each first channel 6.1 forms an individual cooling circuit, thereby effectively acting on the entire molding slider 2.4 and the product. Multiple first channels 6.1 are provided and are spaced apart in the length direction of the automotive hidden door handle 19 to ensure cooling of its side and bottom surfaces in the length direction.

[0059] Further references Figure 7 As shown, specifically, the second cooling structure includes a second channel 7.1 extending vertically and close to both sides of the vehicle hidden door handle 19, a third channel 7.2 communicating with the periphery of the lower molded block, and a spiral blade 7.3 placed in the second channel 7.1. The second channel 7.1 communicates with the third channel 7.2, and the spiral blade 7.3 defines a spiral path within the second channel 7.1. Since the end of the vehicle hidden door handle 19 needs to be formed with a concave-convex feature 20 that cooperates with the door or other components, and this feature 20 corresponds to the parting between the upper molded block and the lower molded block, the spiral path is provided to provide targeted cooling for this feature 20. The spiral path facilitates rapid cooling circulation and sufficient cooling in the vicinity of the feature 20.

[0060] like Figure 8 As shown, in some other embodiments, in order to ensure the stability of mold opening, the lower mold plate 2.1 is provided with a first rotating shaft 8.2, the first rotating shaft 8.2 is covered with a damping sleeve 8.1 and a rotating block 8, and the ejector plate 4 is provided with a first abutting block 9 corresponding to the lower end of the rotating block 8.

[0061] The upper template 1.1 is provided with a limiting rod 11 that fits on the outer boundary of the ejector plate 4, and the lower template 2.1 is also provided with a second abutting block 10. The first abutting block 9 and the second abutting block 10 are arranged on both sides of the limiting rod 11. The rotating block 8 abuts against one side of the limiting rod 11 in the mold closing state, and the trajectory of the limiting rod 11 and the rotating block 8 are not tangent.

[0062] Preferably, in the mold-closed state, the limiting rod 11 extends downward from the upper mold plate 1.1 to the bottom. Through the above improvements, the limiting rod 11 also passes through the outer boundary of the lower mold plate 2.1 in the mold-closed state. The first abutment block 9 and the second abutment block 10 constrain the vertical movement of the limiting rod 11 to ensure the stability of the upper mold 1's movement. The limiting rod 11 is preferably set on both sides of the opposite corner of the mold to guide the mold opening action. During the mold opening process, the limiting rod 11 is also located in the ejection stroke of the ejector plate 4.

[0063] In addition, in the mold-closed state, the limiting rod 11 and the first abutting block 9 also abut against the rotating block 8. At this time, the rotating block 8 swings downward, and the limiting rod 11 is specifically located on the rotation path of the rotating block 8. Through the above improvements, the interaction between the first abutting block 9, the limiting rod 11 and the rotating block 8 enables the ejector plate 4 to play a reliable limiting role in the mold-closed state. For example, if the ejector plate 4 has an upward movement, the first abutting block 9 will push the rotating block 8 upward, and the rotating block 8 will be stopped on the limiting rod 11, thereby limiting the movement of the ejector plate 4. In addition, by swinging the rotating block 8, the position where the first abutting block 9, the limiting rod 11 and the rotating block 8 abut against each other is set as the mold-closed position of the ejector plate 4.

[0064] By limiting the movement of the ejector plate 4 as described above, it also ensures that after the upper mold assembly 1 reaches the mold opening position, the limiting rod 11 disengages from the stop block 8. At this time, the ejector plate 4 moves again, and the first abutting block 9 pushes the ejector plate 4 upward and the rotating block 8 tilts upward. When the mold closes again, the upper limiting rod 11 abuts the rotating block 8 downward and presses the rotating block 8 back to the tilted position of the mold opening state, thereby reasonably constraining the mold opening action of the entire mold.

[0065] The damping sleeve 8.1 serves to dampen the rotating block 8, preventing it from excessively deflecting under the action of the first abutment block 9 or the limit rod 11, thus preventing the rotating block 8 from returning to the predetermined deflection position when the mold is closed or opened.

[0066] like Figure 9 As shown, specifically, the outer boundary of the upper mold plate 1.1 is provided with a T-shaped block 12, and the outer boundary of the lower mold plate 2.1 is rotatably provided with two clamping blocks 13 that cooperate with the T-shaped block 12. Each clamping block 13 is provided with a second rotating shaft, and a spring 14 is provided between the two clamping blocks 13. The two clamping blocks 13 are covered with a mounting seat 15, and the two clamping blocks 13 are restricted to rotate within the mounting seat 15. As the upper mold group 1 and the lower mold group 2 close, the T-shaped block 12 and the two clamping blocks 13 cooperate with each other and provide resistance during the mold opening action. In addition, the further purpose of the cooperation between the T-shaped block 12 and the two clamping blocks 13 is to maintain the tightness of the fit between the upper mold group 1 and the lower mold group 2 in the mold closing state.

[0067] Optionally, a tie rod 16 is detachably provided between the outer boundaries of the upper mold 1 and the lower mold plate 2.1. The tie rod 16 is preferably fixed by bolts. The tie rod 16 can be configured to be assembled in the mold closed state to prevent the mold from leaking during injection molding.

[0068] like Figure 4 and Figure 8 As shown, specifically, the ejector plate 4 is provided with a contact block 17, and the lower module 2 includes a base plate. The base plate is provided with a positioning sensor 18 that is positioned opposite to the contact block 17. Through the above improvements, the positioning of the ejector plate 4 is ensured, and the positioning signal is used to provide the operator with the means to operate the rotating block 8.

[0069] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
